On January 11, the members of the epidemic prevention and control flow team discussed the work at the front line headquarters of the "0107" epidemic disposal and transfer in Longgang District, Shenzhen. The units interviewed provide the site for the circulation of the map. On the morning of January 11, the members of the epidemic prevention and control team carefully checked the surveillance video in the monitoring room of a shopping mall in Buji Street, Longgang District. Shenzhen Evening News reporter Cheng Wenli read the special client Shenzhen News Network, January 17, 2022 (Shenzhen Evening News reporter Cheng Wenli) "Stop, shoot down; stop, rewind back to the previous frame..." Recently, in the monitoring room of a shopping mall in Buji Street, Longgang District, a low, decisive command sounded from time to time, and the quiet air revealed a tense and serious atmosphere. Liu Wenchi's eyes were tightly fixed on the monitoring screen, his fingers kept pressing the "play" and "pause" buttons, and he had just finished an all-night shift, and his eyes were covered with blood. Beside him, it was his colleague Lin Xun, who was also staring at the screen, holding up his mobile phone in his hand while watching and shooting. Liu Wenchi and Lin Xun are members of the "0107" epidemic prevention and control flow, and their job is to track the possible close contact and sub-close contact of the confirmed cases of the new crown, in other words, they are the "detectives" who track the new crown virus. 1 night and day, meticulous epidemic prevention and control At 10 o'clock on January 11, after ending the daily fixed morning meeting, the two people rushed to a shopping mall in Buji Street, Longgang District, where the confirmed case of the new crown had stayed, to carry out a new round of video investigation. In the morning, they looked at surveillance footage to check who might have been in contact with the mall in the trajectory of the confirmed case's behavior. The reporter accompanied them to the scene. The surveillance footage was only 20 minutes long, but hundreds of people passed through the footage. Among them, there are families who spend the weekend, there are young children who laugh and play, there are couples who talk sweetly and laugh... But a brief passing passing by may give the cunning virus a chance. "There can be no slack in the face of the new crown virus, and we must ensure that we find and find all potential contacts so that people can be safe." Liu Wenchi told reporters. In just 20 minutes of surveillance video, Liu Wenchi and Lin Xun watched and shot, frame by frame, for two hours, recording the citizens who may have been affected by the virus one by one. "Today is already fast. Yesterday I viewed a video with surveillance dead ends, I had to call up more surveillance footage to corroborate it, I stared at the screen for five or six hours, and my eyes were spent. On the way back to the headquarters, Liu Wenchi introduced to reporters that viewing the surveillance video is only a very basic work in the circulation, after returning to the command, it is necessary to further sort out and conduct professional research and judgment, and then cooperate with public security, streets and other departments to contact close contacts one by one, and carry out follow-up interviews, medical tests and a series of work. 2 Use the "golden eye of fire" to make the virus invisible Virus can not see, can not touch, where do they come from? Where to go? Where will you hide? All of this requires the flow agent, known as the "Sherlock Holmes" of the viral world, to strip away the cocoon and sort out the complete chain of transmission from a mess. "Circulation" is the abbreviation of "epidemiological investigation" and is the key to epidemic control. Lin Haiduan, captain of the 7th team of the "0107" epidemic situation handling frontline command of the frontline command of the epidemic situation in Longgang District, Shenzhen, introduced that the objects of circulation include "people" and "places", that is, for suspected cases, confirmed cases, asymptomatic infected persons, those who have had close contact with or joint exposure to the above personnel and suspected polluted environments, and key places. And those who only rub shoulders with the virus in the vast sea of people are like a drop of water in the sea, how to find a needle in a haystack? Lin Haiduan said that calling is the most efficient way to grasp the basic situation and core information of the flow target at the first time, and sometimes a phone call takes an hour or two. Some of the transfer objects can not remember or can not clearly describe the trajectory of the action, the flow team will visit the scene, face to face inquiry, and with the help of payment records, ride records and other information to help recall and corroborate. No matter how cunning the virus, there will always be clues. When the trajectory of the confirmed case is clear, the members of the circulation team will go to the key places involved to restore the route, conduct a detailed investigation of the layout, ventilation, and personnel density, etc., to determine whether there is a risk of virus spread. And watching the monitoring is even more indispensable, and the "golden eye of fire" will determine the close contact crowd. "The members of the squad are on standby 24 hours a day and are ready to go." Lin Haiduan introduced that because the flow team went deep into the forefront of the epidemic, once it was put into work, it was fully protective and all-out, could not eat and drink, could not go to the bathroom, and could not determine when the work would end, sometimes it was a whole day, "without completing the whole process can not collect troops." "The information collected by the circulation adjustment plays an important role in effectively curbing the epidemic, and after the confirmed case is found, the circulation group needs to form a preliminary circulation report of more than ten pages within 24 hours, and constantly update and supplement dynamically." Ye Bili, head of the epidemic information group of the "0107" epidemic disposal and circulation front-line command in Longgang District, Shenzhen, introduced that each flow control team is responsible for different cases, and whether there is an intersection between the cases and whether it is on the same transmission chain, it is necessary for the epidemic information group as the "central system" to quickly clarify the massive clues collected by the flow control group, and further verify and track the feedback and organize the corresponding data, so as to provide a scientific basis for the command to study and judge the epidemic situation and implement prevention and control measures. Ye Bili said that the epidemic information group will receive hundreds of documents and materials every day, and it is necessary to quickly sort out clear and clear clues from them. 3 Spread the net, run to the front of the virus to go to 8:30 on the same day, the reporter came to the "0107" epidemic disposal frontline command center in Longgang District, Buji Street, the staff has long been in place, while nibbling on the bread in their hands, while discussing the work at hand, they have just finished an all-night busy. After briefly summarizing and briefing on the progress of last night's key work, they quickly rushed to their respective posts to carry out a new day of anti-epidemic fighting. It is understood that the district "0107" epidemic disposal circulation front line command is divided into a number of working groups, including the circulation group, the epidemic information group, the close connection group, the elimination group, the testing group, the logistics support group, etc., which not only covers the entire chain of the circulation adjustment work, but also includes a series of disposal actions such as follow-up risk analysis and assessment, site control, and elimination, and behind each case is a massive amount of work. At the same time, the headquarters will be set up on the front line of the outbreak, and everyone will eat and live and work together every day, which is convenient for the first time to go to the scene to carry out the handling of the epidemic situation, but also facilitate communication and coordination with each other, "The division of labor between different groups is clear, everyone is orderly, busy and not chaotic." "We are not big detectives who can catch 'criminals' in a single turn of their brains, but only to collect materials and restore every scene in a down-to-earth manner." The relevant person in charge of the command headquarters said: "We must not only track the new crown virus, but also run to the front of the virus transmission chain to completely surround and annihilate the virus." "4 being transferred is not the same as being infected, please actively cooperate with Lin Haiduan's introduction, track the new crown virus, the flow of investigators rushed to the forefront, to some extent determine the direction of epidemic prevention and control, only by obtaining real and effective information and trajectory, can we scientifically determine the source of infection, assess the dynamics of the epidemic, and provide a scientific basis for formulating correct prevention and control measures." For the question of whether the personal information and privacy of the target of the circulation are safe, Ye Bili told reporters that she can rest assured. She said that the flow investigators are very professional, and all aspects of the work also ensure the security of the personal information of the circulation targets through the encryption of investigation reports, computer encryption, and the use of internal software to transmit information. Ye Bili stressed to reporters that being transferred is not the same as being infected, and the public should not panic when receiving a mobile phone call or encountering a visit from a circulation person, please be sure to cooperate, carefully review the recent itinerary, and answer truthfully, "As long as you join hands, you will definitely be able to defeat the epidemic." ”
